consists of a synchronization signal section 1, a function setting section 2, a destination terminal designation section 3, and an end signal section 4. The function setting section 2 displays the types of control and service signals such as selection signals, response status notification signals, bus connection request signals, data reception status notification signals, and disconnection confirmation display signals, and furthermore, in the case of selection signals, one pair The distinction between single communication and broadcast communication is also displayed. Destination terminal designation section 3
performs the following display according to the signal type set in the function setting section 2. That is, if the signal type set in the function setting section 2 is a selection signal and 1
In the case of one-to-one communication, the destination terminal designation section 3 displays one destination terminal number as a normal character dial (note that this setting is performed at the originating terminal).
When the signal type set in the function setting section 2 is broadcast communication, the destination terminal designation section 3 displays the destination terminal with which communication should be made. The destination terminal specifying unit 3 has a plurality of bit positions, and each bit position is associated with a terminal in advance. By setting the bit position of the destination terminal to be communicated to "1," The destination terminal is displayed (note that this setting is done on the originating terminal). When the signal type set in the function setting section 2 is a response state notification signal, the destination terminal designation section 3 displays the response states of a plurality of destination terminals with which to communicate. As in the case above, the response status is displayed by setting the bit position corresponding to the terminal as "1" or "0", depending on whether data can be received or not.
(This setting is done in the exchange). When the signal type set in the function setting unit 2 is a path connection request signal, the destination terminal designation unit 3 displays the destination terminal that actually receives the broadcast communication. The setting of the display of the destination terminal is performed by setting the bit position corresponding to the terminal in the destination terminal designation section 3 to "1" in the same manner as in the above case (this setting is performed at the originating terminal). When the signal type set in the function setting unit 2 is a data reception status notification signal, the destination terminal designation unit 3 displays the data reception status of a plurality of terminals during broadcast communication. To set the display, as in the previous case, set the bit position corresponding to the terminal.
This is done by setting "1" or "0" depending on whether the reception condition is good or bad (this setting is done in the exchange). Function setting section 2
When the signal type set to is a disconnection confirmation display signal, the destination terminal designation unit 3 displays the destination terminal that sent the disconnection confirmation signal. As in the case described above, the display is set by displaying "1" in the bit position corresponding to the terminal in the destination terminal designation section 3 (this setting is performed at the exchange).

Send. If terminals T 1 and T 2 are ready to receive data, response signal 14 ((1; N))
is sent back to exchange 6, and if it cannot be received ((
1; OFF)) or ((repeat of 01; FF)) is returned. Based on the returned signal, the exchange 6 sets the response status notification signal in the signal format shown in Figure 1, displays the response status of each destination terminal as "0" and "1", and sends it to the originating terminal T0 . do. For example, if both terminals T 1 and T 2 are in a data receivable state, the exchange 6 sends a response state notification signal 15 ((SYN, SYN, 0010, 110...
0, +; OFF)) is sent to the originating terminal T 0 . When the path connection instruction signal 16 is sent from the terminal T0 , path connection is performed only to the destination terminal specified by the signal 16, and broadcast communication is possible with the destination terminal that is in the state of being able to receive data. Become. When the broadcast communication path is set in this way, the exchange 6 sends a communication enable signal 17 ((1; ON)) back to the originating terminal T 0 . In response, the originating terminal T 0 starts sending communication data to the terminating terminals T 1 and T 2 . In this communication phase, the destination terminals T 1 and T 2 indicate the data reception status using, for example, a specific bit pattern ((repetition of “01”; ON)).
Notify the exchange using The signal is monitored by the exchange, and the result is set in the function setting section 2 in the signal format shown in Fig. 1 to indicate that it is a data reception status notification signal (011*), and the terminal compatible bit of the destination terminal specification section 3 is set. By setting "1" or "0" in the position, the terminal T 0 is notified of whether the data reception status is good or bad.

報通信信号方式。[Scope of Claims] 1. In broadcast communication in which the same information is transmitted from one terminal to multiple other terminals, from the originating terminal that requests broadcast connection to the multiple destination terminals that are the partners of the broadcast communication Controls and services related to the terminating terminal that should be exchanged between the originating terminal and the exchange, such as terminating terminal selection information for notifying the exchange, and response information for notifying the originating terminal of the response status of the terminating terminal called by the exchange. A broadcast communication signal system characterized in that information is sent and received by a signal having a function setting part representing the type of information and a terminal designation part representing a plurality of destination terminals. 2. The signal to be sent and received includes a synchronization signal section, a function setting section, a destination terminal designation section, and a termination signal section,
The function setting section receives a selection signal, a response state notification signal,
Displays the types of control and service signals such as path connection request signals, data reception status notification signals, disconnection confirmation display signals, etc., and the destination terminal designation section displays all destination terminals related to the signal type set in the function setting section. A broadcast communication signaling system according to claim 1, characterized in that:
